Where is BL-12 located?

BL-12, also known as Fengmen, is located 1.5 cun lateral to the second thoracic vertebra (T2). This point is traditionally used in acupuncture to strengthen the defensive qi (Wei Qi) and is associated with respiratory issues and the exterior.

When palpating for this acupuncture point, practitioners locate the spinous process of T2, which serves as a reliable landmark. From there, measuring 1.5 cun laterally, the point can be effectively identified for needle insertion. Understanding the precise location of BL-12 is crucial for practitioners, as it impacts the efficacy of treatments aimed at conditions related to the lung and immune system.

The other locations provided in the options do not correspond to BL-12's established anatomical placement, which emphasizes the importance of accurate anatomical knowledge in acupuncture practice. Knowing these specifics helps avoid confusion and ensures that treatment is delivered at the correct site.
